Reuters (10/31, Pittman) reports that, according to a review of 14 studies published online Oct. 30 in PLoS One, online groups and social media may be a source of support for troubled teens who may be at increased risk for suicide and self-harm. However, they may also heighten those risks by exposing those adolescents to endorsements of self-harm. In some cases, online groups and social media may also harbor cyber-bullies who pick on vulnerable teens.

The NPR (10/31, Shute) “Shots” blog reports that the review also found a strong association “between online forums and increased risk of suicide, a risk not found with other forms of social networking.”

Medscape (10/31, Osterweil) reports that research published online in the Annals of Oncology indicate that during “the year after a cancer diagnosis, adolescents and young adults are at more than twice the risk of attempting or committing suicide.”

HealthDay (10/31) reports that researchers looked at data on about 8 million Swedish people “aged 15 to 30.” The investigators “found that those with a cancer diagnosis had a 60 percent greater risk of suicide or attempted suicide compared to similar young people without cancer.” The researchers found that “the risk peaked the first year after diagnosis, when it was 150 percent higher.”

Medwire (10/30, Grasmo) reports that, according to a study published online Oct. 19 in the journal Acta Psychiatrica Scandinavica, “patients with bipolar disorder who reside in the United States have a higher parental incidence of bipolar disorder [BD] and depression than those who live in Europe.” The analysis of self-reported data from 525 patients with BD during the years 1995–2002 revealed that “21% of US patients had one parent with a history of bipolar disorder, compared with 10% of European patients, while in 15% versus 4% of patients both parents had bipolar or unipolar depression.”

MedPage Today (10/30, Petrochko) reports that, according to an oral presentation given at the annual conference of the American Academy of Pediatrics, “participation in extracurricular activities, sports or otherwise, may be protective against bullying behaviors in children.” After analyzing data on some 62,215 youngsters ranging in age from six to 17, researchers found that “students who engaged in a nonsport extracurricular activity and played sports were significantly less likely to engage in bullying (odds ratio 0.67, 95% CI 0.57-0.79).”

HealthDay (10/26, Norton) reported that youngsters who have sustained head injuries or concussions appear to “have a much higher-than-average rate of depression,” according to a study presented at the national conference of the American Academy of Pediatrics. Researchers came to this conclusion after analyzing data from “a 2007 nationally representative study covering nearly 82,000” youngsters and adolescents younger than age 18.

Medscape (10/28, McNamara) quotes the study’s lead author, who said, “Our take-home message is that knowledge of this association may help parents and” physicians “identify children at risk for depression and initiate therapy of this treatable” condition.

Kids, Teens With Concussions May Need Short Break From School. The New York Times (10/27, Hoffman) “Well” blog reported that yesterday at its annual conference as well as online in the journal Pediatrics, “the American Academy of Pediatrics issuedrecommendations (10/23) for ‘return to learn’ checklists to alert doctors, school administrators and parents to potential cognitive and academic challenges to students who have suffered concussions.”

The Time (10/27, Sifferlin) “Healthland” blog reported that even though kids “may appear to be physically normal after having a concussion, they may actually have trouble learning new information and retaining it.” Returning to school too quickly “may exacerbate these symptoms.” The guidelines recommend that children with particularly severe symptoms may need to stay home from school. Previous research has shown that it may take up to three weeks before a child is fully recovered from a concussion.
